[目的]寻求防治水稻纹枯病的有效药剂。[方法]在水稻破口期分别施用250 g/L嘧菌酯SC 240 ml/hm2、30%己唑醇SC 225 g/hm2、30%己唑醇SC 225 g/hm2+250 g/L嘧菌酯SC 225 ml/hm2、75%肟菌酯·戊唑醇WG 150 g/hm2、300 g/L苯醚甲环唑·丙环唑EC 300 ml/hm2、10%井冈霉素A SPX 3600 g/hm2，隔7 d再施药1次，调查几种杀菌剂对水稻纹枯病的防治效果。[结果]30%己唑醇SC 225 g/hm2+250 g/L嘧菌酯SC 225 ml/hm2对水稻纹枯病的防治效果最好，第2次药后14 d的防效为87.53%；其次是30%己唑醇SC 225 g/hm2、300 g/L苯醚甲环唑·丙环唑EC 300 ml/hm2，防治效果分别为79.03%、78.92%；而75%肟菌酯·戊唑醇WG 150 g/hm2、10%井冈霉素A SPX 3600 g/hm2、250 g/L嘧菌酯SC 240 ml/hm2防治效果较差。几种药剂在水稻破口抽穗期用药安全性均较好。[结论]30%己唑醇SC 225 g/hm2+250 g/L嘧菌酯SC 225 ml/hm2可以作为今后防治水稻纹枯病的替代农药，在生产上进一步推广使用。
[目的]尋求防治水稻紋枯病的有效藥劑。[方法]在水稻破口期分彆施用250 g/L嘧菌酯SC 240 ml/hm2、30%己唑醇SC 225 g/hm2、30%己唑醇SC 225 g/hm2+250 g/L嘧菌酯SC 225 ml/hm2、75%肟菌酯·戊唑醇WG 150 g/hm2、300 g/L苯醚甲環唑·丙環唑EC 300 ml/hm2、10%井岡黴素A SPX 3600 g/hm2，隔7 d再施藥1次，調查幾種殺菌劑對水稻紋枯病的防治效果。[結果]30%己唑醇SC 225 g/hm2+250 g/L嘧菌酯SC 225 ml/hm2對水稻紋枯病的防治效果最好，第2次藥後14 d的防效為87.53%；其次是30%己唑醇SC 225 g/hm2、300 g/L苯醚甲環唑·丙環唑EC 300 ml/hm2，防治效果分彆為79.03%、78.92%；而75%肟菌酯·戊唑醇WG 150 g/hm2、10%井岡黴素A SPX 3600 g/hm2、250 g/L嘧菌酯SC 240 ml/hm2防治效果較差。幾種藥劑在水稻破口抽穗期用藥安全性均較好。[結論]30%己唑醇SC 225 g/hm2+250 g/L嘧菌酯SC 225 ml/hm2可以作為今後防治水稻紋枯病的替代農藥，在生產上進一步推廣使用。

Objective The aim of this study was to search for effective chemicals to control rice sheath blight. [Method] 250 g/L Azoxystrobin SC (240 ml/hm2 ) , 30%Hexaconazole SC (225 g/hm2), 30% Hexa-conazole SC(225 g/hm2)+250 g/L Azoxys-trobin SC (225 ml/hm2),75% Trifloxys-trobin·Tebuconazole WG ( 150 g/hm2 ) , 300 g/L Difenoconazole ·Propi-conazole EC (300 ml/hm2), 10% Jin-gangmycin-SPX (3 600 g/hm2) were sprayed respec-tively in rice breach period, and once ag-ain after 7 days, in or-der to tinvestigate-the control effect of these fungicides ag-ainst rice sheath blight. [Result] 30%Hexaconazole SC (225 g/hm2)+250 g/L A-zoxystrobin SC (225 ml/hm2) had the best control effect against rice sheath blight, and the control effi-ciency was 87.53%on the 14th day after the second spraying. 30%Hexaconazole SC (225 g/hm2) and 300 g/L Difenoconazole·Propiconazole EC ( 300 ml/hm2) had the better control effect a-gainst rice sheath blight, and the control effi-ciencywas 79.03%and 78.92%, respectively. The control ef-fects of 75%Trifloxystrobin· Tebuconazole WG (150 g/hm2), 10% Jin-gangmycin SPX (3 600 g/hm2) and 250 g/L Azoxystrobin SC (240 ml/hm2)a-gainst rice sheath blight were the worst. These fungic-ides were relatively safe to the rice plants in breach period and heading pe-riod. [Conclusion] 30%Hexaconazole SC (225 g/hm2) + 250 g/L Azoxystrobin SC (225 m l/hm2) can be used in the pro-duction as an alternative pestic ide to con-trol rices heath blight in future.
